It's been six days since CVD-2021-33909 was patched in RHEL, what's the holdup for Stream 8?
by Steven Rosenberg 29 Jul '21

29 Jul '21

This bug in the kernel was patched in RHEL on 7/20. Every other mainstream Linux distro patched it that day or the day after. That includes Rocky and Alma. https://access.redhat.com/security/cve/CVE-2021-33909 It's still not patched six days later in CentOS Stream 8. This Bugzilla entry makes it clear that when it comes to security, CentOS Stream falls behind RHEL. But this far behind? https://bugzilla.redhat.com/show_bug.cgi?id=1975182 This doesn't make a good argument for Stream being a viable CentOS Linux replacement.

Old CentOS 6.3 grub.conf
by Jerry Geis 28 Jul '21

28 Jul '21

I am trying to "add" an entry to grub.conf on CentOS 6.3 - and change the default=0 to default=1 # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,0) # kernel /boot/vmlinuz-version ro root=/dev/sda1 # initrd /boot/initrd-[generic-]version.img #boot=/dev/sda default=1 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.32-279.el6.x86_64) root (hd0,0) kernel /boot/vmlinuz-2.6.32-279.el6.x86_64 ro root=UUID=09337d96-de39-43f1-99c2-8a6a1fadd465 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet initrd /boot/initramfs-2.6.32-279.el6.x86_64.img title Boot Other root (hd0,0) kernel /boot/vmlinuz initrd /boot/initrd I then run "grub-install /dev/sda" and reboot. If I cursor down - my new title is present - but the default is still the first title. What did I miss ? Thanks, jerry

by Leon Fauster 26 Jul '21

26 Jul '21

FYI and everyone on C8S: cloud-init does run on deployed cloud vm's anymore succesfully after update (it was rebased from 20. to 21.). Fix: before rebooting run "cloud-init clean" -- Leon

Folio Infobase
by J Martin Rushton 26 Jul '21

26 Jul '21

Does anyone know any way to read .nfo files from Folio infobases. The best suggestion I've seen so far is to run up a VM with Windows 98 on it, does anyone know where I can get a copy of that! BTW, these are not the .nfo files used to describe scenes. -- J Martin Rushton MBCS

yum quiet not really quiet anymore?
by Gionatan Danti 24 Jul '21

24 Jul '21

Hi all, I noticed that "yum -q" (or "dnf" -q) on CentOS 8 is not really quiet anymore. For example (notiche the "upgraded" line): [root@localhost cron.d]# yum upgrade -y -q Upgraded: python3-perf-4.18.0-305.10.2.el8_4.x86_64 While yum historically had issue with the quiet option [1], this specific issue seems new to me. Do you have any suggestion (short of redirecting stdout to /dev/null)? Thanks. -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it email: g.danti(a)assyoma.it - info(a)assyoma.it GPG public key ID: FF5F32A8

OT: firefox question
by Valeri Galtsev 24 Jul '21

24 Jul '21

Dear Experts, My question is OT, as it is related to firefox, not CentOS system per se. Even more: my firefox runs on FreeBSD workstation. But I figured this list have largest likelihood of having experts in firefox (as well as on other things), so... My firefox behavior changed after one of recent updates.. When one logs in to website that is locked using web password (e.g., set in .htacess/.htpasswd in apache), one gives username/password once. Then firefox remembers that while firefox is running, and you don't have to give credentials (though authentication does happen behind the scenes all the time since). But not anymore for me at least on my (FreeBSD) workstation: in the morning I discover firefox (though it had not been restarted) asks yet again credentials to websites I have been logged to. As if firefox purges credentials to websites after some period of time (or inactivity on those websites). This stared happening not long ago after one of updates firefox is known to release annoyingly often (as in: mozilla foundation forgot the meaning of the word "release" which means well debugged code some time about decade ago...). I tried to find relevant setting in GUI preferences to no avail (maybe it is just me?), and hope, experts know deeper lying preferences, and may point me to relevant one. All in all, I'm forced back onto my pursuit for replacement for firefox browser... Thanks a lot for all your answers. And my apologies for rant (which I was not able to separate due to my frustration...).

Hi, I am confused between CentOS Linux and CentOS Stream as per https://www.centos.org/download/. Please guide me on which one I need to use in the production environment. Is there a difference between CentOS Linux and CentOS Stream? Thanks in advance and I look forward to hearing from you. Best Regards, Kaushal

Annoyances with sound
by mark 23 Jul '21

23 Jul '21

Hi, folks, Running C7, updated the beginning of this month. KDE, I go to the start menu->multimedia. and select kmix, the pretty cursor bounces for a while, then apparently ends with nothing running. Nothing in .xerrors. I try selecting audacity - which I don't trust, given that the last time, weeks ago, that I ran it from the command line, after about 5 min, it hung my system (16G RAM, Core I-7) so hard I had to power cycle. From the start menu... I get a popup "an error has occured." What's going on here? mark

CentOS8 nouveau errors
by Bill Gee 21 Jul '21

21 Jul '21

I am running the stream version of CentOS 8 on a system that hosts a bunch of VirtualBox guests. Recently, like about a month ago, a problem started showing up. When working at the console, the system is almost completely unresponsive. In a terminal session, any key that you press might show up a minute later. Any mouse movement might show up a minute later. About every ten seconds the screen switches to a completely different display for maybe a few tens of milliseconds and then switches back. This happens so fast it is almost subliminal. The log fills with tens of thousands of messages per day that look like this: Jul 21 07:21:06 vmhost2 kernel: Hardware name: Supermicro C7SIM-Q/C7SIM-Q, BIOS 1.2a 06/02/2017 Jul 21 07:21:06 vmhost2 kernel: Workqueue: events_unbound nv50_disp_atomic_commit_work [nouveau] Jul 21 07:21:06 vmhost2 kernel: RIP: 0010:nv50_dmac_wait+0x1e1/0x230 [nouveau] Jul 21 07:21:06 vmhost2 kernel: Code: 8d 48 04 48 89 4a 68 c7 00 00 00 00 20 49 8b 46 38 41 c7 86 20 01 00 00 00 00 00 0 0 49 89 46 68 e8 d4 fc ff ff e9 76 fe ff ff <0f> 0b b8 92 ff ff ff e9 ed fe ff ff 49 8b be 80 00 00 00 e8 b7 fc Jul 21 07:21:06 vmhost2 kernel: RSP: 0018:ffff9ab3c2077d60 EFLAGS: 00010282 Jul 21 07:21:06 vmhost2 kernel: RAX: ffffffffffffff92 RBX: ffff9ab3c2077d60 RCX: 0000000000000000 Jul 21 07:21:06 vmhost2 kernel: RDX: ffffffffffffff92 RSI: ffff9ab3c2077ca0 RDI: ffff9ab3c2077d40 Jul 21 07:21:06 vmhost2 kernel: RBP: 0000000000000002 R08: 0000000000000000 R09: ffffffffc0365fd0 Jul 21 07:21:06 vmhost2 kernel: R10: 0000000000000006 R11: ffffffffc03733c0 R12: 00000000fffffffb Jul 21 07:21:06 vmhost2 kernel: R13: ffff8c141b820b68 R14: ffff8c141b820ba8 R15: ffff8c1144d21e00 Jul 21 07:21:06 vmhost2 kernel: FS: 0000000000000000(0000) GS:ffff8c142fd80000(0000) knlGS:0000000000000000 Jul 21 07:21:06 vmhost2 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Jul 21 07:21:06 vmhost2 kernel: CR2: 000055e49fe63ef0 CR3: 00000001a5410000 CR4: 00000000000006e0 Jul 21 07:21:06 vmhost2 kernel: Call Trace: Jul 21 07:21:06 vmhost2 kernel: base507c_update+0x2f/0x70 [nouveau] Jul 21 07:21:06 vmhost2 kernel: nv50_disp_atomic_commit_wndw.isra.16+0x5f/0x80 [nouveau] Jul 21 07:21:06 vmhost2 kernel: nv50_disp_atomic_commit_tail+0x669/0x9b0 [nouveau] Jul 21 07:21:06 vmhost2 kernel: process_one_work+0x1a7/0x360 Jul 21 07:21:06 vmhost2 kernel: worker_thread+0x30/0x390 Jul 21 07:21:06 vmhost2 kernel: ? create_worker+0x1a0/0x1a0 Jul 21 07:21:06 vmhost2 kernel: kthread+0x116/0x130 Jul 21 07:21:06 vmhost2 kernel: ? kthread_flush_work_fn+0x10/0x10 Jul 21 07:21:06 vmhost2 kernel: ret_from_fork+0x35/0x40 Jul 21 07:21:06 vmhost2 kernel: ---[ end trace 43122b13e20cf558 ]--- Jul 21 07:21:08 vmhost2 kernel: nouveau 0000:01:00.0: DRM: base-0: timeout The daily logwatch report has thousands of lines like this: --------------------- Kernel Begin ------------------------ WARNING: Kernel Errors Present WARNING: CPU: 0 PID: 131209 at drivers/gpu/drm/n ...: 201 Time(s) WARNING: CPU: 0 PID: 131356 at drivers/gpu/drm/n ...: 450 Time(s) WARNING: CPU: 0 PID: 132285 at drivers/gpu/drm/n ...: 3 Time(s) WARNING: CPU: 0 PID: 15274 at drivers/gpu/drm/no ...: 1245 Time(s) WARNING: CPU: 0 PID: 15808 at drivers/gpu/drm/no ...: 144 Time(s) WARNING: CPU: 0 PID: 62 at drivers/gpu/drm/nouve ...: 1080 Time(s) WARNING: CPU: 1 PID: 131209 at drivers/gpu/drm/n ...: 336 Time(s) WARNING: CPU: 1 PID: 131356 at drivers/gpu/drm/n ...: 828 Time(s) WARNING: CPU: 1 PID: 132030 at drivers/gpu/drm/n ...: 18 Time(s) WARNING: CPU: 1 PID: 132285 at drivers/gpu/drm/n ...: 12 Time(s) WARNING: CPU: 1 PID: 15274 at drivers/gpu/drm/no ...: 903 Time(s) WARNING: CPU: 1 PID: 15808 at drivers/gpu/drm/no ...: 108 Time(s) (repeat for 2 megabytes of text) With all VB guests stopped, htop shows CPU usage in the range of 1% or less.
